[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Embodiment 1

[0026] Please refer to Figures 1-6 , the magnetic clutch braking device, including the device body 100, and a first housing 200 and a second housing 300 are respectively arranged on the outer side of the device body 100;

[0027] An installation component 400 is provided between the first housing 200 and the second housing 300. The installation component 400 includes an installation block 401 and an installation groove 402. The installation block 401 is located on the side of the first housing 200 and is fixed to the first housing 200. The installation groove 402 is formed in the second housing 300, and the cross-sectional shape of the installation groove 402 is adapted to the cross-sectional shape of the installation block 401. When the first housing 200 and the second housing 300 move towards the device body 100 for installation, the first housing 200 drives the installation block 401 fixedly connected thereto to move into the installation groove 402 in the second housing 300. A storage groove 403 is formed inside the installation block 401, and a clamping block 405 is connected to the side of the storage groove 403 through a first spring 404. When the installation block 401 moves into the installation groove 402 in the second housing 300, at this time, the first housing 200 drives the clamping block 405 thereon to move together, so that the clamping block 405 is squeezed by the inner wall on the side of the installation groove 402, and the clamping block 405 then squeezes the first spring 404 fixedly connected thereto and moves into the installation groove 402. A clamping groove 406 is formed on the side of the installation groove 402, and a through groove 407 is formed on the side of the storage groove 403. A pulling block 409 is connected to the side of the second housing 300 through a second spring 408. A pressing rod 410 is fixedly connected to the side of the pulling block 409. There are two second springs 408, and the two second springs 408 are symmetrically distributed with respect to the pressing rod 410. The cross-sectional shape of the pressing rod 410 is adapted to the cross-sectional shape of the through groove 407. When the clamping block 405 then squeezes the first spring 404 fixedly connected thereto and moves into the installation groove 402, the pulling block 409 is then pulled. The pulling block 409 then stretches the second spring 408 fixedly connected thereto, thereby driving the pressing rod 410 fixedly connected to the pulling block 409 to move. At this time, the pressing rod 410 moves away from the clamping groove 406, and the installation block 401 continues to drive the clamping block 405 to move into the installation groove 402. When the clamping block 405 moves to the clamping groove 406, the clamping block 405 loses the restriction of the inner wall of the installation groove 402, and the clamping block 405 then moves into the clamping groove 406 under the action of the second spring 408 to complete the installation. Then, the pulling block 409 is released, so that the pressing rod 410 is reset under the action of the second spring 408. At this time, the pressing rod 410 can pass through the inside of the through groove 407 and the first spring 404, thereby pressing the clamping block 405 tightly into the clamping groove 406. The stability of the device after installation is improved, and the impact on the device is reduced. When it needs to be disassembled, the pulling block 409 is pulled to cancel the restriction on the clamping block 405, and then the first housing 200 and the second housing 300 are pulled, thereby completing the disassembly of the first housing 200 and the second housing 300, so as to facilitate the next installation operation and make the device more convenient to use.

[0028] During use, housing one 200 and housing two 300 move towards the device body 100. When performing the installation operation, housing one 200 drives the mounting block 401 fixedly connected thereto to move into the mounting groove 402 in housing two 300. At this time, housing one 200 drives the clamping block 405 thereon to move together, causing the clamping block 405 to be squeezed by the inner wall of the side of the mounting groove 402. The clamping block 405 then squeezes the first spring 404 fixedly connected thereto and moves into the mounting groove 402. Subsequently, the pulling block 409 is pulled, and the pulling block 409 immediately stretches the second spring 408 fixedly connected thereto, thereby driving the pressure rod 410 fixedly connected to the pulling block 409 to move. At this time, the pressure rod 410 moves away from the card slot 406, and the mounting block 401 continues to drive the clamping block 405 to move into the mounting groove 402. When the clamping block 405 moves to the card slot 406, the clamping block 405 loses the restriction of the inner wall of the mounting groove 402, and the clamping block 405 thus moves into the card slot 406 under the action of the second spring 408 to complete the installation. Subsequently, the pulling block 409 is released, causing the pressure rod 410 to reset under the action of the second spring 408. At this time, the pressure rod 410 can pass through the through slot 407 and the inside of the first spring 404, thereby pressing the clamping block 405 tightly into the card slot 406. When it is necessary to disassemble it, the pulling block 409 is pulled to cancel the restriction on the clamping block 405, and then housing one 200 and housing two 300 are pulled to complete the disassembly of housing one 200 and housing two 300. Embodiment Two

[0029] Please refer to Figures 1-6 On the basis of Embodiment One, a locking assembly 500 is provided between housing one 200 and housing two 300. The locking assembly 500 includes a bolt 501. A first threaded groove 502 is formed on housing two 300, and a second threaded groove 503 is formed on the mounting block 401. When the device is installed, the first threaded groove 502 on housing two 300 moves to the position of the second threaded groove 503 on the mounting block 401, and the first threaded groove 502 and the second threaded groove 503 are in an overlapping state. Subsequently, by installing the bolt 501 into the first threaded groove 502 and the second threaded groove 503, the bolt 501 can squeeze the clamping block 405, thereby further locking the clamping block 405 and further improving the stability of the device after installation.

[0030] During use, on the basis of Embodiment One, when the device is installed, the first threaded groove 502 on housing two 300 moves to the position of the second threaded groove 503 on the mounting block 401, and the first threaded groove 502 and the second threaded groove 503 are in an overlapping state. Subsequently, by installing the bolt 501 into the first threaded groove 502 and the second threaded groove 503, the bolt 501 can squeeze the clamping block 405, thereby further locking the clamping block 405.

[0031] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
